And I tried to select File ->Profile ASP.NET as describe on the site,But it gave ma security realted problem. Actully I am a local admin user, how can it be possible? Any ideas ?

"Application attempted to perform an operation not allowed by the security policy.To grant this applicaiton the required permission, contact your system administrator, or use the Microsoft.NET Framework Configuration tool.

If you click Continue, the application will ignore this error and attempt to continue.If you click Quit, the application will close immediately.

Basic paradigm on debugging Microsoft technologies:-Debug_Security ~ Admin Privilege, technically it is more than that of Admin. In debug mode, you can actually see the passwords too.

To keep long story short, please run everything in local administrator mode, and let us know what it is saying.
